DS1040Z-B50+

Overview

The DS1040Z-B50+ is a single-emitter programmable delay line IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a total available delay of 250ns across five taps, with the first tap delayed by 50ns and subsequent taps incremented by 50ns each. The device operates on a single 4.75V to 5.25V supply voltage and is housed in an 8-SOIC package (0.154 inch width). Designed for surface mount installation, it functions within a commercial temperature range of 0°C to 70°C. This component belongs to the DS1040 family and supports programmable delay configurations suitable for timing signal management applications.

Feature Summary

• Programmable single-emitter architecture allowing flexible tap configuration
• Five distinct output taps providing precise incremental delay steps
• Compact 8-SOIC surface-mount packaging for space-constrained designs

Applications

• Timing signal distribution networks requiring specific tap delays
• Clock skew compensation in digital systems
• Pulse shaping and synchronization circuits

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as standard listings often reference the DS1040Z-250+. Confirm RoHS3 compliance and check for obsolescence status, as this product family may have discontinuation notices. Ensure the supplier source matches the original manufacturer or authorized distributor to guarantee authenticity and traceability.

Selection Notes

Select this component when a fixed 250ns total delay with 50ns increments is required. Compare against other members of the DS1040 series if different total delay values or tap counts are needed. Verify that the 8-SOIC package dimensions fit the PCB layout constraints and that the 5V supply voltage aligns with the system power rails.

Part Context

This part belongs to the DS1040 family of programmable delay lines from Maxim Integrated, now part of Analog Devices. These devices are designed for applications requiring precise, adjustable time delays without external components. The Z suffix typically indicates a lead-free, RoHS-compliant variant within the standard SOIC package offering.

Replacement Considerations

Check for direct substitutes within the DS1040 family with compatible pinouts and electrical characteristics. Verify if alternative delay line ICs from other manufacturers offer similar 5-tap architectures and 5V operation while meeting the same package and thermal requirements.
